obliquely striate, less noticeable on the middle: basal abdominal 

 segment very narrow compared with the next. Pygidium long, 

 narrowed to tip, and barely constricted a little before tip. Face 

 with dense white hair, darker above and mostly brownish or gray on 

 the rest of the body, but venter and legs with white hair. Length, 12 

 to 14 mm. 



In some the face-marks are all connected and the supraclypeal 

 mark elongate. The male is smaller (10 mm.), a clypeal and a supra- 

 clypeal spot, and one each side on face; there is no spot on the post- 

 scutellum (some females have a broken spot on the postscutellum), 

 Hve bands on the abdomen, the first segment unmarked, and the last 

 band less concave in front than the others; hind tibiae with dark spot 

 near tip, hind femora wholly black. Clypeal hair-lobes narrow, re- 

 mote; pygidium less narrowed, and not constricted near tip; the 

 enclosure more polished in the middle than in the female.

 body Academy Science, Salem. Four specimens. 



Close to C. compada; the 9 with the clypeus produced and with 

 the two large lamellae below of the same shape; the cf with a pointed 

 clypeal margin. Both sexes are more red than C. compada, and of a 

 size larger; in the female the clypeal process is much broader pro- 

 portionally than in C. compada, there are large reddish yellow spots 

 on the sides of metathorax, and a median yellow spot behind on the 

 first segment of abdomen; the apical band of" the second segment is 

 plainly angularly indented in middle, the pj^gidial area is proportion- 

 ally broader, and broader near base than in C. compada, basal ventral 

 segment reddish; punctuation and other marks as in C. compada. 

 The male also has spots on metanotum and on middle of the first 

 segment of abdomen. 



The true C. compada also occurs in Texas.
